Patented Feb. 1C, l93l entree srATEs PATENT orrica EMANUEL J'. PERRY, OF NEW BEDFORD, MASSACHUSETTS, ASSIGNOH'IO THE AMERICAN LAUNDRY MACHINERY COMPANY, OF CINCINNATI, OHIO, A CORIPORATION OF OHIO CENTRIFUGAL EXTRACTOR Application filed. DecemberSl, 1928. SeriaFNo. 329,510.

This invention relates to underdriven exprove the basket mounting and riving means in a manner to improve the lubrication system and enable the basket to be readily removed from and applied to its supporting parts.

In the drawings, Fig. 1 1s a sectional elevation through one arrangement embodying the invention; Fig. 2 is a detail sectional elevation of the roller bearing on a larger scale; and Fig. 3is a section as in the horizontal I plane of line 3-3, Fig. 1.

' The relatively stationary curb 1 is suspended by three rods 2 from the tops of posts or' columns 3 with universal mountings 4 at top and bottom, all to permit precession, as is usual. At one side said curb has a bracket 5 to support suitable driving means, such as the able post, pillar or spindle 7 around which- 5 the basket turns.

1 center 1O telescoped over the post 7. On the spindle 15, the upper bearings taking the radial motor 6.

, In the curb is rigidlv mounted a non-rotat- The basket, marked 8, has the usual foraminous outer wall 9 and at its isprovided with an upstanding sleeve are secured "upperand lower inner bearing races 11, 12 cooperating with bearing rollers 13 lying between them and the outer races 1% an the lower bearings the vertical strains. By removing a detachable cap 16 from sleeve 10 and taking oil the unit 17 the basket may be lifted off from spindle 7, as will'be' readily understood.

At the bottom of the spindle the curb carries an annular shield or guard 18 (Fig. 2)

entering an opening in the basket bottom. Lubricant is supplied to spindle bearings through the 1plugged opening 19, traveling down along e spindle past the bearings to its bottom, when it is held from escape by said guard.

Attached to the bottom of the basket is a pulley 20 around which travel drive ropes or elts '21 which pass through a curb opening 1ato the motor pulley 22.- Said pulley 20 is of'driven form and also serves as the brake drum, its inner surface being gripped by suitable expanding friction brake mechanism, marked generally 23 and including an actuator 24 operated by a shaft 25 having an arm 26 below the curb where it may be connected to any suitable controlling or operating mechanism such as the lever 23a. The details of the brake mechanism however may be of any suitable or preferred description and form no part of the invention and have been more or less conventionally illustrated in Fig. 3.

Pulley 2O lies in an annular recess 27 formed within a depending portion of the curb around the post 7 the Wall of said portion, of course,.including the belt opening 10. Also the curb at its bottom has its fioor sloping outwardly. 'to a channel 28 leading to the drain 29, "to thereby conduct the extracted liquid to an outlet and away from recess 27 v This arrangement simplifies the construc- I tion and assembly of the basket and spindle, and also the lubrication problem is to a large extent reduced to very simple form.

Having described my invention, I claim:

In an extractor, a frame, a curb frame, a

curb carried thereby and having a-n upwardly dished bottom with a central opening, universal supporting linkage between said c and curb frame, a hollow boss secured to said bottom at said central opening and provided with a lateral belt drive opening, a shaft support carried by said boss and projecting up- .said curb, a basket, a central sleeve carried thereby, upper and lower bearing structures between said sleeve and said shaft, a pulley secured to the bottom of saidbasket and surrounding said shaft support, a motormount ed on the curb frame, and a belt drive between said motor and said pulley.

Intestimony whereof I hereby 'atfix my signature.

EMANUEL J. PERRY.
